SydneyFRB 20240304B crossed 10 billion light years to reach Earth.
It is more than twice as far as the next-farthest known fast radio burst.
South Africa’s MeerKAT caught it on 4 March 2024, and James Webb located its host galaxy at redshift 2.148.
Manisha Caleb’s team says only that the host galaxy is consistent with a magnetar origin.
Radio telescopes’ sensitivity limits have kept bursts beyond redshift 1 scarce, Caleb’s team says.
How each outlet framed it
- 404 Media leans favorable
- frames the FRB as the most distant ever detected, 'three billion years after the Big Bang', with light-travel detail
